youre going to get a bunch of varied responses. basically, what weve seem to conclude is that your skill level, board type (stiffness, camber profile), snow conditions and the amount of people on the slope will all affect what you want to do.

for me personally, i like to keep some pressure on one edge or another. there is merit to the argument that your board is faster when youre not pressuring an edge. where i ride, the snow conditions and the amount of people i need to maneuver around simply dont allow for it to be a safe option to be totally flat based.

your backend feels squirrely that's your clue, are a bit in the backseat; shift to the front seat…
Edit: also make sure you are stacked and parallel with close shoulders and hips. You were likely rotated open and in the backseat....the usual set up for a scorpion

I actually do better leaning back a bit and pulling the weight up off my front foot like riding pow if I flatbase, now going off a jump - I dont know what I do

One more flatbasing comment... (I talk about groomers. I think its clear that we all flatbase in pow).
Had this discussion with my husband. As mentioned before, I stay quite centered with slightly more weight on the front foot. He says, that this is ok at my (in his opinion rather slow) high speed, but if he's up at real high speed (over 65mph), he stays well in the hind seat. His argument was that you've less base contact and thus less risk that an edge could contact slightly uneven snow. Heard the same thing of a race pro, who recomnended me to put more weight on the hind foot to make the (Rc) board a more stable ride. Even if this sounds reasonable, it surprised me cause it's against all I've read so far. I'll never be able to make this observation cause I'm too scared to hit this speeds. But I'd be very interested if some of you guys, that ride such speeds have similar impressions.

I think he is wrong. It's just that high speeds have a very big stabilizing effect. As has been mentioned before, if the weight is back, the board will want to pivot if there is a disturbance.

I've only ever caught an edge at relatively low speeds (knock on wood).

We have already established the fact that in good, soft groomed powder flat basing is easy but due to drag, I will believe 60MPH when I see it.

Measured with a Garmin Etrex (which is using doppler effect, you can expect 1mph accuracy). Conditions were excellent, the trail was freshly groomed, the snow very, very fast. Heck, I've done 45mph on a beginner trail.

this "to flatbase or not to flatbase" topic seems to hit a sensitive spot, kind of a religious thing... Anyway. I actually didn't want to resume the flatbase discussion but was interested if someone else does this "more weight on hind foot" at top speed.

BTW. Just cause one thinks it's reckless doesn't automatically mean that there's not someone out there who does so

on a camber its more weight to the front, increasingly so with speed..thats what i do anyhow and i havent biffed on the cattrack in 20 yrs

going thru this thread, to me, any controversy on all this is just funny

Yeah, lots of science here for such a simple issue. I don't really pay attention to what I do though, I just ride. I haven't had such problems either. I refuse to teach new people how to board though, I suck at it and get mad if they get frustrated or give up. I just make them take lessons so I can enjoy my day.
